What is Hay fever, and Dust allergy?

Hay fever, also known as allergic rhinitis or nasal allergies, is an allergic reaction to pollen (a fine powder from plants), dust particles, or tiny flecks of skin and saliva shed by cats, dogs, and other animals with fur or feathers, typically when it comes into contact with the mouth, nose, eyes and throat.

It shows cold-like signs and symptoms, such as a runny nose, sinus, sneezing, and itchy red eyes.

Dust allergies are caused by dust mites which is microscopic creatures that are smaller than one millimetre. They are often found in a person’s home. 

They thrive in warm, and humid conditions, and dies in low humidity levels or extreme temperatures.

Dust allergy sign and symptoms are similar to those of pollen allergies, such as sneezing, runny, stuffy nose, and red, itchy, watery eyes.
